It is generated from the same database
polish IRCnet servers use to generate their I-lines (access lines).
As new networks come to life, their admins (or users)
tell us to add them,
hence I hope the list is quite complete.
If you see any errors or omissions, let me know.

Due to repeated requests from IPv6 tunnel brokers I also prepared
list of our K-lines for *@cidr ranges, so it can be used
to deny tunnels requested for K-line evasion. These are only active K-lines
for full IPv4 hosts or networks.
